40/60/80?

I’m almost embarassed to ask - ex level 2 newbie that i am - but what is 40/60/80 ? Why is everyone in the level 3 forum going on about it ? Or should i just wait for my books to arrive?

Way to estimate your overall score based on the three ranges of performance that CFAI reports to you. (low = 40%; mid = 60%; high = 80%).

i see…thanks… i still dont get it, but im guessing i will by the time i crush level 3 in jun 10
